What is already in the game right now?

I know this is early alpha an so that not everything from the trailer is in game but I would like to know what is already in. Like if the mechs are in what types of armours and weapons (how many or if just one exemplar of each type) and the covents and how much of the character progression is in.

Weapons: Assault Rifle; Pistol.
Armors: Tactical; Commando; Assault.
Starter Tutorial; A lot of side quests; a decent length main quest that is gonna get longer.
No Mechs/Glider/Jetpack/ActivatedAbilities/In Depth Party System/Crafting/Space
Loot/XP is NOT shared.
Plenty of enemies ranging from 5 all the way to freaking 48.
Most quests do not have quest markers/journal entries so you will need to depend on other players and guides developed by the dedicated testers.
